Specific implementation mode
The present invention is derived from following observation experience:The use of the tool of conventional available system or the controlled displacement of equipment is complicated And increase operating cost.
It now will be about the description of the drawings controlled type shift mechanism not limited the scope of the invention with scope.
Although hereafter will about the rocker arm shaft of the tractor for hoisting tool describe the present invention, this field it is common It will be appreciated by the skilled person that the mechanism of the present invention is applicable to the displacement of the tool or equipment using the power from motor Any operation.Fig. 1 shows the tractor rocker arm shaft 1 with the lift arm 3 activated by lever mechanism 2, for being connected to tool.Ginseng According to attached drawing, it is particularly shown controlled type shift mechanism in fig. 2.Controlled type shift mechanism includes mounting plate 12, connector 14, fortune Dynamic restriction element 16 and retainer 18.Actuating signal is received by connector 4, controlled type shift mechanism can make from motor The torque of drive shaft (not shown) is transferred to the driven shaft coordinated with lift arm, to be connected to the tool of lift arm 3 It is displaced to target location from the off position of lift arm 3.
As shown in Fig. 2, connector 14 can connect drive shaft (not shown) and driven shaft 20.Driven shaft 20 is at one end Place coordinates with connector 14, and coordinates with lift arm 3 at the other end.Although being wanted it should be appreciated that having been described above driven shaft 20 Coordinate with the lift arm 3 of rocker arm shaft, but driven shaft 20 can coordinate with any other connecting rod, equipment or tool.As shown in Fig. 2, Drive shaft coordinates with motor 22, torque is transferred to driven shaft 20 from motor 22 by connector 14.Fig. 3 is illustrated and motor 22 Drive shaft cooperation connector 14.Connector 14 can transmit torsion on the axial direction of the operative axis along connector 14 Square.As shown in fig. 4 to fig. 6, sawtooth is limited on connector 14 so that sawtooth is parallel to the operative axis of connector 14. Under normal conditions, sawtooth is internal sawtooth 19, as shown in Fig. 4 to Fig. 5, is limited at hollow (hollow) of connector 14 It is interior.Alternatively, sawtooth is the external sawtooth (being not shown in the accompanying drawings) being limited on the outer surface of connector 14.Sawtooth energy The complementary buttress for enough making connector 14 and being limited in drive shaft and driven shaft 20 coordinates.Optionally, connector 14 passes through key Slot and bond structure are engaged by locking with drive shaft and driven shaft 20.Particularly as shown in Figures 4 to 6, retainer 18 and connector 14 Cooperation, and it is approximately perpendicular to the operative axis of connector 14.Retainer 18 can correspond in operative configuration by lift arm 3 The required predetermined angle in target location is displaced to away from angularly shifting.
As shown in Fig. 2, mounting plate 12 is positioned such that connector 14 is sandwiched between mounting plate 12 and motor 22.Especially Ground is shown in Fig. 7 and Fig. 8, and mounting plate 12 has first surface 23a and second surface 23b parallel to each other.Mounting plate 12 by with It is set to so that first surface 22a is adjacent to motor 22.Mounting plate 12 define connector support opening 24 and hole 26a, 26b and 26c.Connector support opening 24 is configured such that coordinate between connector 14 and driven shaft 20.Each hole 26a, 26b It is defined as to be spaced apart at a predetermined distance from each other with 26c.Mounting plate 12 is retained interval point by spacer 28 as shown in Figure 8 Open configuration.Spacer 28 and the support device 28a as shown in Figure 3 of motor 22 coordinate.In addition, the second surface of mounting plate 12 23b includes from second surface 23b mounting pins 30 outstanding.Under normal conditions, mounting pin 30 and mounting plate 12 are integral, and with Each hole 26a, 26b and 26c are equidistant.
As shown in FIG. 9, movement restriction element 16 includes constraint component 32, and the constraint component 32 is required controlled It can be releasably assemblied in the operative configuration of formula shift mechanism in hole 26a, 26b or 26c to be protruded from first surface 23a.About Beam component 32 integrally or is press fit into the opening being arranged in movement restriction element 16 with movement restriction element 16.Such as Shown in Fig. 10, movement restriction element 16 defines the mounting groove being located in mounting pin 30 for that will move restriction element 16 31.As shown in Figure 10 and Figure 11, movement restriction element 16 is assemblied in by nut 34 and pin 34a arrangements on mounting groove 31.It is right Lift arm is displaced to the required predetermined displacement in target location by Ying Yu, and constraint component 32 is positioned in hole 26a, in 26b and 26c One in.In alternate embodiments, constraint component 32 is can be releasably assemblied in hole 26a, one in 26b and 26c In bolt form.
In the mode of operation of controlled type shift mechanism, connector 14 connects drive shaft and driven with the way of torque of transmission Axis 20.When motor is activated, in torque transmission process, connector 14 is rotated along its operative axis.Retainer 18 Rotation can angularly shift retainer 18 along the plane for the operative axis for being approximately perpendicular to connector 14 again.Retainer (18) angular displacement continues, until when realizing the target location 3 of lift arm, retainer 18 abuts limiting component 32.Constraint The angular displacement of the further limit stops 18 after abutting limiting component 32 of component 32.Lift arm 3 is locked in target location Realized by locking device (not shown), the locking device be from by electronic locking device, Pneumatic locking device, It is selected in the group of hydraulic lock assembly and mechanical locking composition.By in hole 26a, changing constriction between 26b and 26c The position of part 32 can change the target location of lift arm 3.Lift arm 3 is displaced to target location from off position.It is abutting The operation for leading to terminate motor 22 of the angular displacement of limit stops 18 after constraint component 32.
Therefore, controlled type shift mechanism of the invention facilitates the accurate positionin of tool while minimizing in the positioning of tool Error.
